Introduction1 fields
- Background
- Thirteen of Britain's American colonies broke with the mother country in 1776 and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. During the 19th and 20th centuries, 37 new states were added as the nation expanded across the North American continent and acquired a number of overseas possessions. Two of the most traumatic experiences in the nation's history were the Civil War (1861-65), in which a northern Union of states defeated a secessionist Confederacy of 11 southern slave states, and the Great Depression of the 1930s, an economic downturn during which about a quarter of the labor force lost its jobs. Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world's most powerful nation state. Since the end of World War II, the economy has achieved relatively steady growth, low unemployment, and rapid advances in technology.

McKinley is the highest point (6,190 m; 20,308 ft) in North America, and Death Valley is the lowest point (-86 m; -282 ft) note 2: the western US coast and the southern coast of Alaska lie along the Ring of Fire, which is a belt bordering the Pacific Ocean that contains about 75% of the world's volcanoes and up to 90% of the world's earthquakes note 3: the Aleutian Islands are a chain of volcanic islands that divide the Bering Sea (north) from the main Pacific Ocean (south); they extend about 1,800 km (1,118 mi) westward from the Alaskan Peninsula; the archipelago consists of 14 larger islands, 55 smaller islands, and hundreds of islets; there are 41 active volcanoes on the islands, which together form a large northern section of the Ring of Fire note 4: Mammoth Cave, in west-central Kentucky, is the world's longest known cave system with more than 650 km (405 miles) of surveyed passageways, which is nearly twice as long as the second-longest cave system, the Sac Actun underwater cave in Mexico (see "Geography - note" under Mexico) note 5: Kazumura Cave on the island of Hawaii is the world's longest and deepest lava-tube cave; it has been surveyed at 66 km (41 mi) long and 1,102 m (3,614 ft) deep note 6: Bracken Cave outside San Antonio, Texas is the world's largest bat cave and the summer home to the largest colony of bats in the world; an estimated 20 million Mexican free-tailed bats roost in the cave from March to October, making it the world's largest known concentration of mammals
